“President Trump is about to make an obscure state official, Brad Utter, Senior Historian/Curator from New York State Committee on Geographic Names a famous person for a day.“

The problem Trump faces is his proposal is contrary to NYCRR 8 § 182.1 (a)(2) which specifically says, “Euphonious and other suitable names of Indian, Dutch and other linguistic origin shall be retained.”

The word Ontario originates from Indigenous languages of the Iroquoian family, originally used to describe Lake Ontario before being adopted for the land and eventually the province. Linguists and historians attribute the name to two primary linguistic roots:

1. The Huron (Wyandot) Origin

• Root Word: Ontarí:io (or Ontare)
• Translation: “Great Lake” or “Large Lake”
• Breakdown: In the Wyandot language, ontare translates directly to “lake,” while the suffix -io translates to “it is large” or “great”. [1, 2, 3]

2. The Iroquois (Haudenosaunee) Origin

• Root Word: Kanadario (also cited as Skanadario or Onitariio)
• Translation: “Sparkling Water” or “Beautiful Lake”
• Significance: This described the shimmering, clear nature of the easternmost Great Lake. The translation is highly fitting, as freshwater lakes and rivers make up roughly one-fifth of the province’s total area. [1, 2, 3, 4, 5, 6, 7]

Historical Timeline

• 1641: The first recorded European use of “Ontario” appeared on French maps to identify the mass of land on the north shore of Lake Ontario.
• 1867: The name was officially chosen and adopted as the formal title for the province during Canadian Confederation.

The U.S. Board on Geographic Names (BGN) can legally override state geographic names committees, but it rarely does so in practice. Because the BGN holds the final statutory authority to approve names for federal maps and databases, its decisions override state preferences when a conflict arises. However, the federal board heavily prioritizes local and state consensus, treating state boards as essential cooperative partners.

That said, the Lake America move mirrors Trump’s executive order in January 2025, which directed federal agencies to rename the Gulf of Mexico to the Gulf of America. The BGN complied with that directive for the federal geographic names database, and U.S. entities like Google Maps updated their domestic displays accordingly, though the rest of the world did not.

The state might not update to Lake Ontario to Lake America. In 1988, Governor Mario Cuomo instructed New York State Committee on Geographic Names to rename Bad Indian Swamp in Watkins Glen to Catharine Creek Marsh, and was known as such on all state maps and state agencies thereafter. However, the federal government did not rename the wetland to “Queen Catharine Marsh” until 2025.
